Former R.E.M. guitarist Peter Buck and ex-Sleater-Kinney frontwoman Corin Tucker have formed a new band together, as the Portland Mercury reports. Little has been revealed about the group aside from the fact that they're opening for Buck's solo sets at Portland's Secret Society Ballroom tonight and tomorrow. The band also features Scott McCaughey (Young Fresh Fellows, Minus 5), Bill Rieflin (Swans, Ministry), and Kurt Bloch (ex-Fastbacks). Their working name (subject to change) is super-Earth.

As McCaughey told the Mercury, the shows will feature "an entire set of soon-to-be-album-sized new compositions by said Buck/Tucker combine."

In other Corin Tucker news, this year marks the 20th anniversary of her pre-Sleater-Kinney band Heavens to Betsy's album Calculated. It was just reissued on vinyl by Kill Rock Stars. Her most recent release with her latest group, Corin Tucker Band, was 2012's Kill My Blues.
